Here are the accumulated fixes for 7.1-rc1 and a single structural worth of
mentioning separately: Rafael's commit converting tpm_crb from ACPI driver to a platform driver. Starting from this release cycle, the branch with TPM changes mirrored to next is 'for-next-tpm', and patches for keys have their own separate 'for-next-keys' branch. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQRE6pSOnaBC00OEHEIaerohdGur0gUCaezVbgAKCRAaerohdGur 0ggHAQDmhaZ2C3ddAV1WjfXh1YqdWAmqEqoP7ZHAh4OrjyRPTQD+Pc4xl9TSOgHx /9WzzV6AM6fL5RuC2/PO5RvOKF9mswc= =tpJM -----END PGP SIGNATURE----- Merge tag 'for-next-tpm-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd Pull tpm updates from Jarkko Sakkinen: "Here are the accumulated fixes for 7.1-rc1 and a single structural change worth mentioning separately: Rafael's commit converting tpm_crb from ACPI driver to a platform driver" * tag 'for-next-tpm-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd: tpm: tpm_tis: stop transmit if retries are exhausted tpm: tpm_tis: add error logging for data transfer tpm: avoid -Wunused-but-set-variable tpm: Use kfree_sensitive() to free auth session in tpm_dev_release() tpm2-sessions: Fix missing tpm_buf_destroy() in tpm2_read_public() tpm: Fix auth session leak in tpm2_get_random() error path tpm: i2c: atmel: fix block comment formatting tpm_crb: Convert ACPI driver to a platform one tpm: Make tcpci_pm_ops variable static const |

Here is the char/misc/iio and other smaller driver subsystem updates for
7.1-rc1. Lots of stuff in here, all tiny, but relevant for the
different drivers they touch. Major points in here is:
- the usual large set of new IIO drivers and updates for that
subsystem (the large majority of this diffstat)
- lots of comedi driver updates and bugfixes
- coresight driver updates
- interconnect driver updates and additions
- mei driver updates
- binder (both rust and C versions) updates and fixes
- lots of other smaller driver subsystem updates and additions
All of these have been in linux-next for a while with no reported
issues.

spi: Fixes for v7.1
This is quite a big set of fixes, almost all from Johan Hovold who is on an ongoing quest to clean up issues with probe and removal handling in drivers. There isn't anything too concerning here especially with the deregistration stuff which will very rarely get run in production systems since this is all platform devices in the SoC on embedded hardware, but it's all real issues which should be fixed. There's more in flight here. We also have a few other minor fixes, one from Felix Gu along the same lines as Johan's work and a couple of documentation things. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmnrhSUACgkQJNaLcl1U h9C4HwgAgcnZgIZvPQp5mQ0G3sq1udBJQja4zYyQyuZt7o+1qLs/qiPw+KA1HV/C hVXFcns2Uy+Sqmi1fPlVadWsOODcwYz3wfS198Du8y4WqIeynVFYoYvXxQmAJYYW zq0VD9LE/5Y+ONwABzqkfgy7ZvNzykoRgodKPoruqnkYqU0ZH7iY/k7916vxk4+Z +8hCDlG5JHv7Uw1wAuftwnACIhsi4jN3f7wsvA++ac3OXKpDC/0l4JX2gBzPaxfI HaT5+W+tDIDk7IbQmweatMMIoi6cvjttieoh6HLqGdJZF0aI7IgH71CDAB+6fWrx kwZIkX2FL5+mVLA1vCUNjwkZDFS+pg== =MD5+ -----END PGP SIGNATURE----- Merge tag 'spi-fix-v7.1-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "This is quite a big set of fixes, almost all from Johan Hovold who is on an ongoing quest to clean up issues with probe and removal handling in drivers.

Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden to core networking developers. syzbot loves to find bugs in BKL-era code, and noobs try to fix them. If we want to have a fighting chance of surviving the LLM-pocalypse this code needs to find a dedicated owner or get deleted. We've talked about these deletions multiple times in the past and every time someone wanted the code to stay. It is never very clear to me how many of those people actually use the code vs are just nostalgic to see it go. Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code. We were lucky enough to find someone who wants to help with NFC so we're giving that a chance. Let's try to put the rest of this code behind us.

Including fixes from Netfilter.
Steady stream of fixes. Last two weeks feel comparable to the two
weeks before the merge window. Lots of AI-aided bug discovery.
A newer big source is Sashiko/Gemini (Roman Gushchin's system),
which points out issues in existing code during patch review
(maybe 25% of fixes here likely originating from Sashiko).
Nice thing is these are often fixed by the respective maintainers,
not drive-bys.
Current release - new code bugs:
- kconfig: MDIO_PIC64HPSC should depend on ARCH_MICROCHIP
Previous releases - regressions:
- add async ndo_set_rx_mode and switch drivers which we promised
to be called under the per-netdev mutex to it
- dsa: remove duplicate netdev_lock_ops() for conduit ethtool ops
- hv_sock: report EOF instead of -EIO for FIN
- vsock/virtio: fix MSG_PEEK calculation on bytes to copy
Previous releases - always broken:
- ipv6: fix possible UAF in icmpv6_rcv()
- icmp: validate reply type before using icmp_pointers
- af_unix: drop all SCM attributes for SOCKMAP
- netfilter: fix a number of bugs in the osf (OS fingerprinting)
- eth: intel: fix timestamp interrupt configuration for E825C
Misc:
- bunch of data-race annotations

eventpoll: refresh eventpoll_release() fast-path comment
The old comment justified the lockless READ_ONCE(file->f_ep) check with "False positives simply cannot happen because the file is on the way to be removed and nobody ( but eventpoll ) has still a reference to this file." That reasoning was the root of the UAF fixed in "eventpoll: fix ep_remove struct eventpoll / struct file UAF": __ep_remove() could clear f_ep while another close raced past the fast path and freed the watched eventpoll / recycled the struct file slot. With ep_remove() now pinning @file via epi_fget() across the f_ep clear and hlist_del_rcu(), the invariant is re-established for the right reason: anyone who might clear f_ep holds @file alive for the duration, so a NULL observation really does mean no concurrent eventpoll path has work left on this file. Refresh the comment accordingly so the next reader doesn't inherit the broken model.

net: remove ax25 and amateur radio (hamradio) subsystem
Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation and all associated hamradio device drivers from the kernel tree. This set of protocols has long been a huge bug/syzbot magnet, and since nobody stepped up to help us deal with the influx of the AI-generated bug reports we need to move it out of tree to protect our sanity. The code is moved to an out-of-tree repo: https://github.com/linux-netdev/mod-orphan if it's cleaned up and reworked there we can accept it back. Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP, AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN) so that the conditional integration code in arp.c and tun.c continues to compile and work when the out-of-tree modules are loaded.

net: remove ISDN subsystem and Bluetooth CMTP
Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol from the kernel tree. ISDN is a pretty old technology and it's unclear whether anyone still uses it. I went over the last few years of git history and all the commits are either tree-wide conversions or syzbot/static analyzer fixes. When we discussed removal in the past IIRC there were some concerns about ISDN still being used in parts of Germany. Unfortunately, the code base is quite old, none of the current maintainers are familiar with it and AI tools will have a field day finding bugs here. Delete this code and preserve it in an out-of-tree repository for any remaining users: https://github.com/linux-netdev/mod-orphan UAPI constants AF_ISDN/PF_ISDN and the SELinux isdn_socket class are preserved for ABI stability, but the rest of uAPI is removed.

8021q: use RCU for egress QoS mappings
The TX fast path and reporting paths walk egress QoS mappings without RTNL. Convert the mapping lists to RCU-protected pointers, use RCU reader annotations in readers, and defer freeing mapping nodes with an embedded rcu_head. This prepares the egress QoS mapping code for safe removal of mapping nodes in a follow-up change while preserving the current behavior.

NFS: fix writeback in presence of errors
After running xfstest generic/751, in certain conditions, can have a writeback IO stuck while experiencing one of the two patterns. Pattern#1: writeback IO experiences ENOSPC on an offset smaller than the filesize. Example, write offset=0 len=4096 how=unstable OK write offset=8192 len=4096 how=unstable OK write offset=12288 len=4096 how=unstable ENOSPC write offset=4096 len=4096 how=unstable ENOSPC client sends a commit and receives a verifier which is different from the last successful write. It marks pages dirty and writeback retries. But it again send writes unstable and gets into the same pattern, running into the ENOSPC error and sending a commit because writes were sent at unstable. Pattern#2: an unstable write followed by a short write and ENOSPC. write offset=0 len=4096 how=unstable OK write offset=4096 len=4096 how=unstable returns OK but count=100 write offset=4197 len=3996 how=stable returns ENOSPC client send a commit and receives a verifier different from the last unstable write. The same behaviour is retried in a loop. Instead, this patch proposes to identify those conditions and mark requests to be done synchronously instead. Previous solution tried to mark it in the nfs_page, however that's not persistent thus instead mark it in the nfs_open_context. Furthermore, the same problem occurs during localio code path so recognize that IO needs to be done sync in that case as well.

We've finally gotten rid of the struct clk_ops::round_rate() code after months
of effort from Brian Masney. Now the only option is to use determine_rate(),
which is good because that takes a struct argument instead of just a couple
unsigned longs, allowing us to easily modify the way we determine and set rates
in the clk tree.
Beyond that core framework change we've got the typical pile of new SoC clk
driver additions, fixes for clk data and/or adding missing clks because the
consumer driver using those clks wasn't ready, etc. The usual suspects are all
here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers
making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk
driver side of this looks pretty normal.
Core:
- Remove the round_rate() clk op (yay!)
New Drivers:
- ESWIN eic700 SoC clk support
- Econet EN751221 SoC clock/reset support
- Global TCSR, RPMh, and display clock controller support for
the Qualcomm Eliza platform
- TCSR, the multiple global, and the RPMh clock controller
support for the Qualcomm Nord platform
- GPU clock controller support for Qualcomm SM8750
- Video and GPU clock controller support for Qualcomm Glymur
- Global clock controller support for Qualcomm IPQ5210
- Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock
controllers on the SoC
- ExynosAutov920: Add G3D (GPU) clock controller
- Clock driver for the Rockchip RV1103B SoC
- Initial support for the Renesas RZ/G3L (R9A08G046) SoC
- Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC

Fixing livelocks in shrink_dcache_tree()
If shrink_dcache_tree() finds a dentry in the middle of being killed by another thread, it has to wait until the victim finishes dying, gets detached from the tree and ceases to pin its parent. The way we used to deal with that amounted to busy-wait; unfortunately, it's not just inefficient but can lead to reliably reproducible hard livelocks. Solved by having shrink_dentry_tree() attach a completion to such dentry, with dentry_unlist() calling complete() on all objects attached to it. With a bit of care it can be done without growing struct dentry or adding overhead in normal case.

net: cache snapshot entries for ndo_set_rx_mode_async
Add a per-device netdev_hw_addr_list cache (rx_mode_addr_cache) that allows __hw_addr_list_snapshot() and __hw_addr_list_reconcile() to reuse previously allocated entries instead of hitting GFP_ATOMIC on every snapshot cycle. snapshot pops entries from the cache when available, falling back to __hw_addr_create(). reconcile splices both snapshot lists back into the cache via __hw_addr_splice(). The cache is flushed in free_netdev().

net: introduce ndo_set_rx_mode_async and netdev_rx_mode_work
Add ndo_set_rx_mode_async callback that drivers can implement instead of the legacy ndo_set_rx_mode. The legacy callback runs under the netif_addr_lock spinlock with BHs disabled, preventing drivers from sleeping. The async variant runs from a work queue with rtnl_lock and netdev_lock_ops held, in fully sleepable context. When __dev_set_rx_mode() sees ndo_set_rx_mode_async, it schedules netdev_rx_mode_work instead of calling the driver inline. The work function takes two snapshots of each address list (uc/mc) under the addr_lock, then drops the lock and calls the driver with the work copies. After the driver returns, it reconciles the snapshots back to the real lists under the lock. Add netif_rx_mode_sync() to opportunistically execute the pending workqueue update inline, so that rx mode changes are committed before returning to userspace: - dev_change_flags (SIOCSIFFLAGS / RTM_NEWLINK) - dev_set_promiscuity - dev_set_allmulti - dev_ifsioc SIOCADDMULTI / SIOCDELMULTI - do_setlink (RTM_SETLINK) Note that some deep hierarchies still do skip the lower updates via: - dev_uc_sync - dev_mc_sync If we do end up hitting user-visible issues, we can add more calls to netif_rx_mode_sync in specific places. But hopefully we should not, the actual user-visible lists are still synced, it's that just HW state that might be lagging.

net: add address list snapshot and reconciliation infrastructure
Introduce __hw_addr_list_snapshot() and __hw_addr_list_reconcile()
for use by the upcoming ndo_set_rx_mode_async callback.
The async rx_mode path needs to snapshot the device's unicast and
multicast address lists under the addr_lock, hand those snapshots
to the driver (which may sleep), and then propagate any sync_cnt
changes back to the real lists. Two identical snapshots are taken:
a work copy for the driver to pass to __hw_addr_sync_dev() and a
reference copy to compute deltas against.
__hw_addr_list_reconcile() walks the reference snapshot comparing
each entry against the work snapshot to determine what the driver
synced or unsynced. It then applies those deltas to the real list,
handling concurrent modifications:
- If the real entry was concurrently removed but the driver synced
it to hardware (delta > 0), re-insert a stale entry so the next
work run properly unsyncs it from hardware.
- If the entry still exists, apply the delta normally. An entry
whose refcount drops to zero is removed.

pppoe: drop PFC frames
RFC 2516 Section 7 states that Protocol Field Compression (PFC) is NOT
RECOMMENDED for PPPoE. In practice, pppd does not support negotiating
PFC for PPPoE sessions, and the current PPPoE driver assumes an
uncompressed (2-byte) protocol field. However, the generic PPP layer
function ppp_input() is not aware of the negotiation result, and still
accepts PFC frames.
If a peer with a broken implementation or an attacker sends a frame with
a compressed (1-byte) protocol field, the subsequent PPP payload is
shifted by one byte. This causes the network header to be 4-byte
misaligned, which may trigger unaligned access exceptions on some
architectures.
To reduce the attack surface, drop PPPoE PFC frames. Introduce
ppp_skb_is_compressed_proto() helper function to be used in both
ppp_generic.c and pppoe.c to avoid open-coding.

NFSD 7.1 Release Notes
Benjamin Coddington contributed filehandle signing to defend against filehandle-guessing attacks. The server now appends a SipHash-2-4 MAC to each filehandle when the new "sign_fh" export option is enabled. NFSD then verifies filehandles received from clients against the expected MAC; mismatches return NFS error STALE. Chuck Lever converted the entire NLMv4 server-side XDR layer from hand-written C to xdrgen-generated code, spanning roughly thirty patches. XDR functions are generally boilerplate code and are easy to get wrong. The goals of this conversion are improved memory safety, lower maintenance burden, and groundwork for eventual Rust code generation for these functions. Dai Ngo improved pNFS block/SCSI layout robustness with two related changes. SCSI persistent reservation fencing is now tracked per client and per device via an xarray, to avoid both redundant preempt operations on devices already fenced and a potential NFSD deadlock when all nfsd threads are waiting for a layout return. The remaining patches deliver scalability and infrastructure improvements. Sincere thanks to all contributors, reviewers, testers, and bug reporters who participated in the v7.1 NFSD development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmnlF50ACgkQM2qzM29m f5dfHBAAi2o1i9/RA6fmxi2qSV7tkg79viuGFRj3c4cjiW8ZqQXos63zmy6BNMFG joEoirdryUETkrrckXP81HKGSWBQqYjaXeklOw8dggQ8g72HGiqcoT3Ua7L9S7A8 /Db6IwZnJcehHO8XwHV4jSAfIZuvC0iiK02tVrVe/l/9GWcG+bS340GgE9Es2IAW copBGlTwQah+eRvy2hP+Eo3vUTP8Rdebp9iYFI12xqx2x3LquFR01PpjCzotqAvV AcvCPa/AGoSOjcL8idloL8F8mSaOCyx15YJH0lm3hRsPtS/VyXWjKvcejWUh/7PH gHi+5VTsSKbUBj3PJQZU6rBQ67KnwVLZ33KkIF2ZNGllvK0yDGM0UfX/TuaEPjUV 6N0UkRprCHJdrULt9XMXmX3Ddnz1xbYT8CaeIDObw3Ix7SJKedvlLTjvsYCYtsQn 5pkHUuHmr/YAF4AQi/JI4ubZhZ+K3YytNS8YiMUkBWDbPoKzo2yrkzwjGjHdUp0y l8LfEjePAcIpuFQZegERA9CnjIeKb66DJe8da0EwtreY+sejm/S8zbBUhMkXjo6u QwdXXeLX3/zni6Op8vRA5JH//S5ovlQFnkUSvHRItSUrDBRVm+wXD7Vnp9bykKcN leqbSvehnV4PIi0URMvN5ox1WNmsOFIZkv9nv8amyOX8PlRmLoA= =iFl6 -----END PGP SIGNATURE----- Merge tag 'nfsd-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: - filehandle signing to defend against filehandle-guessing attacks (Benjamin Coddington) The server now appends a SipHash-2-4 MAC to each filehandle when the new "sign_fh" export option is enabled.

improvements, updates, and new features. Highlights are:
- new USB power supply driver support (will cause merge conflicts in
drivers/power/supply/Makefile, but it's a simple fix) These changes
did touch outside of drivers/usb/ but got acks from the relevant
mantainers for them.
- dts file updates and conversions
- string function conversions into "safer" ones
- new device quirks
- xhci driver updates
- usb gadget driver minor fixes
- typec driver additions and updates
- small number of thunderbolt driver changes
- dwc3 driver updates and additions of new hardware support
- other minor driver updates
All of these have been in the linux-next tree for a while with no
reported issues

TTY/Serial changes for 7.1-rc1
Here is the set of tty and serial driver changes for 7.1-rc1. Not much here this cycle, biggest thing is the removal of an old driver that never got any actual hardware support (esp32), and the second try to moving the tty ports to their own workqueues (first try was in 7.0-rc1 but was reverted due to problems.)

Pin control changes for the v7.1 kernel cycle:
Core changes:
- Perform basic checks on pin config properties so as not to
allow directly contradictory settings such as setting a pin
to more than one bias or drive mode.
- Handle input-threshold-voltage-microvolt property.
- Introduce pinctrl_gpio_get_config() handling in the core for
SCMI GPIO using pin control.
New drivers:
- GPIO-by-pin control driver (also apperaing in the GPIO pull
request) fulfilling a promise on a comment from
Grant Likely many years ago: "can't GPIO just be a front-end
for pin control?" it turns out it can, if and only if you
design something new from scratch, such as SCMI.
- Broadcom BCM7038 as a pinctrl-single delegate.
- Mobileye EyeQ6Lplus OLB pin controller.
- Qualcomm Eliza and Hawi families TLMM pin controllers.
- Qualcomm SDM670 and Milos family LPASS LPI pin controllers.
- Qualcomm IPQ5210 pin controller.
- Realtek RTD1625 pin controller support.
- Rockchip RV1103B pin controller support.
- Texas Instruments AM62L as a pinctrl-single delegate.
Improvements:
- Set config implementation for the Spacemit K1 pin controller.

mm/sparse: fix comment for section map alignment
The comment in mmzone.h currently details exhaustive per-architecture bit-width lists and explains alignment using min(PAGE_SHIFT, PFN_SECTION_SHIFT). Such details risk falling out of date over time and may inadvertently be left un-updated. We always expect a single section to cover full pages. Therefore, we can safely assume that PFN_SECTION_SHIFT is large enough to accommodate SECTION_MAP_LAST_BIT. We use BUILD_BUG_ON() to ensure this. Update the comment to accurately reflect this consensus, making it clear that we rely on a single section covering full pages.

shmem, userfaultfd: implement shmem uffd operations using vm_uffd_ops
Add filemap_add() and filemap_remove() methods to vm_uffd_ops and use them in __mfill_atomic_pte() to add shmem folios to page cache and remove them in case of error. Implement these methods in shmem along with vm_uffd_ops->alloc_folio() and drop shmem_mfill_atomic_pte(). Since userfaultfd now does not reference any functions from shmem, drop include if linux/shmem_fs.h from mm/userfaultfd.c mfill_atomic_install_pte() is not used anywhere outside of mm/userfaultfd, make it static.

userfaultfd: introduce vm_uffd_ops->alloc_folio()
and use it to refactor mfill_atomic_pte_zeroed_folio() and mfill_atomic_pte_copy(). mfill_atomic_pte_zeroed_folio() and mfill_atomic_pte_copy() perform almost identical actions: * allocate a folio * update folio contents (either copy from userspace of fill with zeros) * update page tables with the new folio Split a __mfill_atomic_pte() helper that handles both cases and uses newly introduced vm_uffd_ops->alloc_folio() to allocate the folio. Pass the ops structure from the callers to __mfill_atomic_pte() to later allow using anon_uffd_ops for MAP_PRIVATE mappings of file-backed VMAs. Note, that the new ops method is called alloc_folio() rather than folio_alloc() to avoid clash with alloc_tag macro folio_alloc().

When userspace resolves a page fault in a shmem VMA with UFFDIO_CONTINUE it needs to get a folio that already exists in the pagecache backing that VMA. Instead of using shmem_get_folio() for that, add a get_folio_noalloc() method to 'struct vm_uffd_ops' that will return a folio if it exists in the VMA's pagecache at given pgoff. Implement get_folio_noalloc() method for shmem and slightly refactor userfaultfd's mfill_get_vma() and mfill_atomic_pte_continue() to support this new API.
